title: Generation of an array of optical bottle beams using a superposition of Bessel beams.
abstract: A procedure for computing the phase transmission function of diffractive optical elements intended to form an array of optical bottle beams is proposed and studied. The procedure is based on a superposition of Bessel beams. We show that the hollow circular beams (optical bottle beams) are suited for trapping transparent spherical micro-objects matched in radius with the beam radius. A series of experiments on trapping transparent micro-objects in the optical bottle arrays is described. Results of an experiment on trapping opaque spherical microparticles in a double optical bottle are reported.
